20250519使用TF卡将NanoPi NEO core开发板刷机为Ubuntu core22.04.3系统完成之后执行poweroff自动关机

1、h3-sd-friendlycore-xenial-4.14-armhf-20210618.img.gz 在WIN10下使用7-ZIP解压缩/ubuntu20.04下使用tar
2、Win32DiskImager.exe 写如32GB的TF卡。【以管理员身份运行】
3、TF卡如果已经做过会有3个磁盘分区，可以使用SD Card Formatter/SDCardFormatterv5_WinEN.zip格式化TF卡。DiskGenius可以尝试。

制作好Ubuntu core22.04.3系统的IMG固件之后，还需要你编辑TF卡中的文件：
1、修改H:\eflasher.conf
autoStart=/mnt/sdcard/friendlycore-jammy
autoExit=true

2、root@NanoPi-NEO-Core:/opt# vi run-eflasher.sh
root@NanoPi-NEO-Core:/opt# cat run-eflasher.sh
poweroff

如果能够直接编辑IMG固件就好了。到时候写TF卡之后不需要每次都来编辑这两个文件。

缘起：在上电之后，TF卡将NanoPi NEO core开发板刷机之后自动关机，安全/保险一点。
【不会丢数据^_】

【你放心吧】生产线的工人只会问你插入TF卡之后上电几分钟刷机完成。【2分钟搞定】
不要想他们会去看DEBUG串口打印信息。

【切记，不需要在H:\eflasher.conf的autoStart项目之后手工输入autoExit项目。conf配置文件有/自带的。^_】
1、使用Win32DiskImager.exe写TF卡之后，将TF卡插入读卡器之后插入到WIN10/WIN11的电脑。
【理论上在ubuntu20.04.6下使用gedit修改也OK的。】
修改H:\eflasher.conf。【具体盘符H以您的电脑为准。^_不通的电脑肯定会变化的！】

C:\TF1emmc-jammy22.04\FriendlyARM\eflasher.conf

; This is the eFlasher configuration file.
; See http://wiki.friendlyarm.com/wiki/index.php/EFlasher for detailed information.

[General]
; Automate OS installation at system startup,
; Use the "autoStart" field to specify the image path or RAW image file,
; The RAW image file can be a gzip compressed file,
; The RAW image file extension must be ".raw" or ".gz",
; Available values: friendlycore-jammy
autoStart=friendlycore-jammy

; If the "autoExit" field set to true, the eflasher-gui will automatically exit after burning or restoring is completed,
; You can do something else after burning or restoring by modifying /opt/run-eflasher.sh.
autoExit=false

; Don't erase the flash before burning, useful if you only want to update part of the system files
disableLowFormatting=false

[UI]
; HDMI overscan option, examples:
; screenSizePercent=auto
; screenSizePercent=90
screenSizePercent=auto

welcomeMessage=
hideMenuButton=false
hideBackupAndRestoreButton=false
hideStatusBar=false
autoRebootWhenSDBeEjected=true

2、将TF卡插入到NanoPi NEO core开发板，使用vi编辑run-eflasher.sh：【加入poweroff关机】
